A worked example

Shown solved, with the whole explanation open: this is what every question here carries.

Describe cloud conceptsEasy

In the shared responsibility model, which factor primarily determines how security responsibilities are divided between a customer and Microsoft?

Correct.

The concept

Responsibility for a workload is split between customer and provider, and where the line falls is not fixed. It moves according to how much of the stack the provider operates on your behalf.

Why this answer

The source states that workload responsibilities vary depending on whether the workload is IaaS, PaaS, SaaS, or on-premises, making the service model the deciding factor.

  • Correct: this is exactly the factor the source identifies as determining the division of responsibility.
  • BOrganization size is never mentioned as a factor in the shared responsibility model.
  • CHeadquarters location does not affect the division of security responsibilities described.
  • DProgramming language choice has no bearing on the shared responsibility division.
